Numerical studies on non-linearity of added resistance and ship motions of KVLCC2 in short and long waves

International Journal of Naval Architecture and Ocean Engineering, 2019
In this study, numerical simulations for the prediction of added resistance for KVLCC2 with varying wave steepness are performed using a Computational Fluid Dynamics (CFD) method and a 3-D linear potential method, and then the non-linearities of added ...

Evaluation of the Effect of Container Ship Characteristics on Added Resistance in Waves

Journal of Marine Science and Engineering, 2020
Added resistance in waves is one of the main causes of an increase in required power when a ship operates in actual service conditions. The assessment of added resistance in waves is important from both an economic and environmental point of view, owing ...

Seismic resistance of existing buildings with added light timber structure storeys

Građevinar, 2022
In the presented paper, the problem of vertical expansions is treated in terms of seismic resistance of structures with added storeys. A large parametric study has been performed, confirming the impact of different number of added storeys, and the change

Calculation of Added Resistance in Oblique Waves

Journal of the Society of Naval Architects of Japan, 1980
The formula for the added resistance of a ship in oblique waves is simplified by the assumption of high frequency of encounter. Numerical computations by the simplified formula are carried out with respect to the Series 60, CB=0.70 model at various heading angles to the wave.

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Bow hull-form optimization in waves of a 66,000 DWT bulk carrier

International Journal of Naval Architecture and Ocean Engineering, 2017
This paper uses optimization techniques to obtain bow hull form of a 66,000 DWT bulk carrier in calm water and in waves. Parametric modification functions of SAC and section shape of DLWL are used for hull form variation.
